Exotic dancer Joslyn Morse, 32, could end up as a key witness for Rodriguez’s heartbroken wife, Cynthia, who accuses him of “extramarital affairs and other misconduct” in her divorce filing in Miami on Monday.

But Morse, who catted around the country with the superstar for months before The Post exposed their relationship last summer, insisted she still cares about him and wishes him well.

The well-muscled Morse said Cynthia’s lawyers have “not as of yet” asked her to testify, but added she’d have no problem taking the stand.

She gave reporters a curt “no comment” at a gas station in Sunny Isles Beach when asked if she had an affair with 32-year-old A-Rod.

“I don’t believe much in life anymore,” Morse answered when asked about her former paramour’s infatuation with Madonna. She did not elaborate.

In other developments:

* Life & Style magazine reported that Madonna has said she’ll attend a party A-Rod is hosting Monday at the 40/40 Club in New York to mark next week’s All-Star Game at Yankee Stadium.

“Madonna knows about the party and is coming,” a source told the magazine.

Life & Style said a spokeswoman for Madonna – whose own marriage is reportedly on the rocks – denies the Material Mom will be there.

* Another woman who is “friends” with Rodriguez, fitness model Alicia Marie, denied that she and the Bomber had been romantically involved.

“She does know A-Rod, they’re very good friends, but nothing romantic,” said Marie’s spokeswoman, Debi Curzio.

Curzio confirmed that Marie had visited a club in Miami with Rodriguez, but did not know if it was a strip joint, as a tipster told The Post.

Marie recently broke up with former baseball player John Rocker, who years ago enraged the Big Apple by making racially charged remarks and slurs about New Yorkers.

Curzio denied that Rocker, another of her clients, had been jealous of Marie’s relationship with Rodriguez.

“Alicia was friends with Alex long before she met John,” Curzio said.

Marie currently is taping an MTV reality show.

* A judge has scheduled Alex and Cynthia to be deposed Tuesday in Miami for a civil lawsuit by a carpet installer who allegedly was bitten on the butt by the Rodriguez’s “large, black dog” Gypsy when he was doing work at the couple’s Coral Gables mansion in 2003.

That’s the day A-Rod is scheduled to play in the All-Star Game, so it is likely the deposition will be postponed yet again, said Brian Rodier, the lawyer for carpet installer Marlon Portillo.

Rodier said Gypsy “did have a reputation for being dangerous,” and should have been kept away from Portillo – who suffered a permanent scar – when he was at the mansion.

“There’s no doubt they knew they had a dangerous dog on their hands,” Rodier said of A-Rod and C-Rod.

But the lawyer also said he believed Rodriguez would “do the right thing” in the case, and hoped it would not be necessary to go to trial.
